What materials would a penguin use in the ice for its nest?

Answer 1

Depending on one of the 18 the species some don't have a nest. Four species live and nest in the Antarctic. The Emperor penguins don't nest, but the male has a pouch between his feet and while the females are out getting food the males put the egg in the pouch keeping it warm. The males stay warm themselves by forming a circle and moving from the inner circle to the outer circle. This way they keep the eggs warm and themselves. Another species of penguins uses rocks and stones found on the beach to make a nest. Others in the southern oceans use ice floes and rocky shores, but they do not nest and lay eggs on the ground.
